MACHINE FOR GUTTNG- REED.

Application led April 11, 1923.l Serial No. 631,456.

This invention-relatesto a machine for operating upon large rods` or pieces of reed, forcing them' through dies to` produce a large number of reeds of relatively small diameter. In the operation of such machines, as heretofore known, the original rod or piece of reed is dividedinto a central core, a plurality of small reeds surrounding the core, and a number ofI pieces of waste formed from the outside of the rod. These several parts are discharged together from the machine, after which they require manual sorting and separation before any further operation can be performed.

It is one important object of my invention to provide mechanical means for automatically separating the three products of the machine as they are delivered from the cutting die, thus avoiding the necessity for manual separation,

Another object of my invention is to provide a machine in which a second feedingl device engages the core as` it leaves one die and advances it to a second die, thus rproviding continuous operation and greatly assisting the final movement of the extreme rear end portion of the rod through the rst die.

Other features of my invention relate to arrangements and combinations of parts which will ybe hereinafter described and more particularly pointed out in the appended claims. n

A preferred form of the invention is shown in the drawings in` which- Fig. l is a side elevation of my improved machine, with parts thereof shown in section;

F ig. 2 is an enlarged side elevation of the The large rod or piece of reed R is fed through a guide to a feeding device comprising a cylindrical sliding member 11 movable by a, yoke 'lever 12 which is regularly oscillated by a feed shaft 13, an eccentric 14, and an eccentric link or c0nnect- ,tively large outer openings 85.

27 to die-head or frame 28. 'A cord 29 is secured to the end ofthe lower equalizing member 26 and passes over a guide pulley 30 on theupper lever, said cord also supporting ka weight T at its lower end. With this construction, the centering jaws 20 have a straight line movement toward and from each other and are always at equal distances `from the airis of the cutting die 3l. The

die 3l is secured in the head 28 by adjust` mg screws 32 and is provided with a central =opening 33, a plurality of small round intermediate ,openings 34 and a series of rela- In the operation of the machine, the thoroughly moistened rod R is forced between the centering jaws 2O and through the cutting die 81 which divides the rod intoa central core C, a plurality of small reeds R and a number of strips lof waste W1 rlhe construction and operation `of the machine as thus far described is of the usual type and forms no part of my `presentV invention,.whichwill now be described.

At the delivery side of the die 31, l provide a sorting and separating device comprising 'an outer conical member 40 held in place by a disc 41lixed to thev die head 28 by bolts 42 and having the small end of its cone abutting thede 81 between thel outer openings and the small reed cutting openings 34. rllhe waste WV passes outside of the conical member while the reeds'lt and the kcore C pass inside of the member 40. An inner conical member 43 is also positioned by the disc 41 and is provided with a hollow cylindrical shank 44 centered in the disc.

The small end of the vconical member 43 engages the die 31 between the small circular openings 34 and the central opening 33. 1

The axial opening through the member 43 and shank 44 is of sufficient size to permit Vtliedisc 41. Obviously the member 18 and 'the'disc 'd1 may befarr'aiig'ed to "discharge the 'reeds R in any desired direction.

My improved :sorting ands'eparating de"- vice thus prevents interiningling 'or the wasteand coreV with the finished reed and delivers 'tliefthre'e 'products separately, thus avoiding 'a large Iamount jot `manual labor.

Tvfhile the Ymachine as thus far described is an important improvement overlthe yprevious practice, a 'further feature or my invention Jrel'aft'esto ythe 'provision or a `second feeding device 5 0 (Fig. 1'), mounted beyond the discharge end 'o'r tlieshanlr ed and actuated by a yoke lever `51 connectediby a linl;

52 to the 'yoke leve'r 12 and eccentric `link 15. Thisieeding'device 5()y engagesthe'core C and advances itjthrough a vbushing 53 'to a second'cuttiii'g'die ,mounted in a seconddie head 54. VAsecond sortingfand separating device55 yis mounted'onthe die'head 54 and corresponds in its several parts to the :sorting device previously described, with the exception that the inner ends or the conical members 'are adapted to the ditiere'nt locations oi the holes or openings in the'second and smaller die.' The Waste WV is delivered outside the devicej55, the reeds Rzfare vcollected Qand delivered through an 'opening in the end of the device 55y and'afsm'aller ,core C2 Vis delivered through the axial openingas previouslydescribed. I, v

1Where the reed i 'ofsufticientfsigze to 1require a third operation, a'third lifeeding device 60, die head 61, and sorting device 62 'may be provided, discharging 'additional waste VW,- reeds IRS: and coreC'. Quitecoinmonly the third cutting head 61 "merely trims the core'G, discharging it asa iinished i reed C3, andi-no reeds R3 are'produ'ced Yfrom the v' third cutting die.

Having described the construction and operation 'of my `improved cutting inachine, the 'advantages thereof `yvill beapparent. The sepa-rate delivery of thedin'ished reed and Waste greatly reduces 'the manual labor andthe continuous operationof 'the machine permits 'me to reduce a rough rod or piece of 'reed R to finished `vreeds RQRZ RS and C3 at asin'gle operation fand y Without manual attention, except to `dispose of the inished [reeds as theyare sortedfanddelivered from the machine. Furthermore, each 'feeding device y'51 and A60 acts vto -jptill the rear end oi the rod R through tliep'receding cutting' die,l aswell 'as y to push the vremaining core through the next "succeeding die.
